Ruby on rails Rails 4在"行动"之前有时不'；工作不好

我的环境

• ruby 2.1.4（出现在2.1.2中）
• Rails 4.1.6（出现在4.1.1中）开发环境

我在操作之前设置@current\u存储

class Store::ApplicationController < ApplicationController
  before_action :set_current_store

  private
  def set_current_store
    Rails.logger.debug "set_current_store is called"
    @current_store = Store.find session[:id]
  end
end

class Store::FooController < Store::ApplicationController
  def index
    @foos = Foo.where(store_id: @current_store.id)
  end
end

类存储：：ApplicationController

如果要从另一个方法调用该方法，请不要将其设为私有class@HisatakeIshibashi，我不是rails超级明星，我只是想给你一个正确的编码方式。如果答案能解决问题，就接受它。。
